示例1: testAtomicPutCreate
func testAtomicPutCreate(t *testing.T, kv store.Store) {
// Use a key in a new directory to ensure Stores will create directories
// that don't yet exist.
key := "testAtomicPutCreate/create"
value := []byte("putcreate")
// AtomicPut the key, previous = nil indicates create.
success, _, err := kv.AtomicPut(key, value, nil, nil)
assert.NoError(t, err)
assert.True(t, success)
// Get should return the value and an incremented index
pair, err := kv.Get(key)
assert.NoError(t, err)
if assert.NotNil(t, pair) {
assert.NotNil(t, pair.Value)
}
assert.Equal(t, pair.Value, value)
// Attempting to create again should fail.
success, _, err = kv.AtomicPut(key, value, nil, nil)
assert.Error(t, store.ErrKeyExists)
assert.False(t, success)
// This CAS should succeed, since it has the value from Get()
success, _, err = kv.AtomicPut(key, []byte("PUTCREATE"), pair, nil)
assert.NoError(t, err)
assert.True(t, success)
}示例2: testAtomicPut
func testAtomicPut(t *testing.T, kv store.Store) {
key := "testAtomicPut"
value := []byte("world")
// Put the key
err := kv.Put(key, value, nil)
assert.NoError(t, err)
// Get should return the value and an incremented index
pair, err := kv.Get(key)
assert.NoError(t, err)
if assert.NotNil(t, pair) {
assert.NotNil(t, pair.Value)
}
assert.Equal(t, pair.Value, value)
assert.NotEqual(t, pair.LastIndex, 0)
// This CAS should fail: previous exists.
success, _, err := kv.AtomicPut(key, []byte("WORLD"), nil, nil)
assert.Error(t, err)
assert.False(t, success)
// This CAS should succeed
success, _, err = kv.AtomicPut(key, []byte("WORLD"), pair, nil)
assert.NoError(t, err)
assert.True(t, success)
// This CAS should fail, key exists.
pair.LastIndex = 6744
success, _, err = kv.AtomicPut(key, []byte("WORLDWORLD"), pair, nil)
assert.Error(t, err)
assert.False(t, success)
}示例3: testAtomicPutWithSlashSuffixKey
func testAtomicPutWithSlashSuffixKey(t *testing.T, kv store.Store) {
k1 := "testAtomicPutWithSlashSuffixKey/key/"
success, _, err := kv.AtomicPut(k1, []byte{}, nil, nil)
assert.Nil(t, err)
